STOP MECHANISM FOR LOOMS.

Specification of Letters Patent.

Patented May11, 1920.

Application filed January 30, 1920. Serial No. 355,039.

To all whom it may concern:

Be it known that I, WILLIAM H. BAHAN, Jr., a citizen of the United States, residing at Union, in the county of Union and State of South Carolina, have invented certain new and useful Improvements in Stop Mechanism for Looms, of which the following is a specification.

This invention relates to the stopping mechanism of looms; and it consists in an improvement to the knock-off lever which operates the shipperlever, the knock-off lever being operatively connected with the slidable frog or slide-block as hereinafter fully described and claimed, and a more satisfactory operation of the said parts being thereby obtained.

In the drawings, Figure 1 is a side or end view of portions of a loom provided with a knock-off lever according to this invention. Fig. 2 is a plan view of the knockofi" lever and the shipper lever.

The loom has a frame 2, a lay 3, and a breast beam 4: of any approved construction. The shipper lever 5 is also of any approved construction, and normally engages with a notched retaining plate 6. When the shipper-lever is moved out of its retaining notch it operates the belt-shifter to stop the loom in the usual way. The shipper-lever is disengaged automatically by the loom by any suitable protector mech anism, which is not a part of the present invention.

A rocker-arm 7 is mounted on the lay 3, and carries a dagger or hunter 8, adapted when in operative position to engage a shoulder 9 on a frog or slide-block 10, and move the latter in the direction of the arrow as the loom beats up. An upwardly projecting finger 12 on the arm 7 is adapted to engage with the usual feeler or binder 14 so that when the shuttle is properly positioned in the box the feeler or hinder will act upon the finger 12 and move the dagger or bunter into inoperative position, improper positioning of the shuttle failing to move the dagger.

When the frog or slide-block is moved by the dagger or bunter, the frog or slide-block engages with the lower end portion 15 of the knock-ofi lever 16 which is pivoted by a pin 17 to the frame 2, and turns the knockoff lever on its pivot. The upper end portion 18 of the knock-off lever then moves the shipper-lever 5 out of its retaining notch so that the loom is stopped. It is found that the frog or slide-block 10 becomes worn and allows the dagger or bunter to strike improperly, and the dagger or bunter sometimes slips over the projection or shoulder 9 on the frog or slide-block when it should engage with the same, and breakouts are thereby occasioned.

In order to overcome this difliculty, a lobe or projection 20 is formed on the lower end portion 15 of the knock-off lever, and is arranged to project under the end of the frog or slide-block 10 so that the two parts are operatively connected together, and the front end of the frog or slide-block is supported by the said lobe, lug or projection.

The frog or slide-block 10 is operatively connected with the protector mechanism by a rod 21 and pivot pin 22, which operate in the usual Way. WVhen the frog or slide-block 10 is thus connected with the knock-off lever, unnecessary stoppage of the loom is prevented and a better action of the stop mechanism is assured.

What I claim is:

In a stop mechanism, a frame,

a frog or slide-block mounted on the frame,

a knockofl lever pivoted to the frame and having a supporting lug on its lower end portion which projects under the front end of the frog or slide block and prevents it from being moved downwardly, a dagger or bunter carried by the lay and arranged to operate the said frog or slide-block, and a shipperlever controlled by the said knock-off lever.

In testimony whereof I have alfixed my signature.

WILLIAM H. BAHAN, JUN.
